IBS advice, tips, help?

So I have self diagnosed myself with IBS. I don’t have health insurance so going to a doctor is not a option for me. My IBS has gotten so severe I am constantly afraid to leave the house. It seems right when I leave the feeling strikes and I need a bathroom immediately. This happens multiple times a day and it’s really interfering with me living a normal life.

Anyone with IBS or knows about it knows any ways I can help make it better?
